Gun Lead Connections
Power Cable
Millermatic Compatible™ Python
®
liquid cooled guns utilize a specially
designed cable with a #6 AWG cable inside a 1/2" (13 mm) diameter hose.
Liquid coolant is used with this cable and the #10 liquid cooled gas cup,
the system is rated at 400 amps @ 60% duty cycle. The welding power
connection is incorporated through the power pin type connector.
The power cable ends are threaded ttings which screw into the gun body
and the power pin connector. These connections utilize a conductive sealant
and are tightened with torque requirements of 100 + 5 IN-LB.
Conduit
The liquid cooled Millermatic Compatible™ Python
®
comes standard with
a poly-lined conduit, for feeding aluminum wire. The longer tting with a
shallow groove is used on the gun end. A set screw located on top of the
gun handle secures the conduit in place. The cabinet end of the conduit is
secured into the Power Pin connector with a set screw.
Gas Hose
The gas hose is pushed over barbed ttings on both gun body and the Power
Pin connector and is secured with a plastic tie wrap.
Coolant Connections
The blue coolant (supply) hose is pushed over a barbed tting on the gun
body and secured with a plastic tie wrap. The red coolant (return) hose
connects through the power cable and the power pin connector.
Both hose ttings are standard coolant style, left-hand threads.
Control Cable
A multi-conductor control cable is used on the liquid cooled Millermatic
Compatible™ Python
®
. The gun end of the cable is secured with a cable
clamp and the wires are connected to the potentiometer, the micro switch,
the motor and the gun body mechanically. Slack is left in the electric cable
as it exits the back of the gun to prevent cable and/or wire breakage. The
cabinet end of the control cable uses a 10-Pin, "X" clocked connector.
